Application filed larch 19, 1910, Serial No. 550,396. Renewed May 4, 1914. Serial No. 886,357.

To all whom. it may concern Be it known that I, O'rro MALCHER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Calculating-Machines, of which the following is a specification.

In an application of Samuel E. Carlin for United States Letters Patent for improve, ments in calculating machines, Serial No. 514,447, there is shown and described a plurality ofoperating shafts for the number bearing members of the totalizers, each of which shafts is provided with a series of nine operating gears. Power shafts are also provided for transmitting motion to the operating shafts and these power shafts are each provided with selector mechanisms individual to the gears on the operating shafts, whereby a variable movement may be imparted to the respective operating shafts. These selector mechanisms are in turn controlled by actuating keys individual to the selector mechanisms, which construction and arrangement necessitates, in the exemplification of the invention set forth in the said application, eighty-one operating keys and a corresponding number of selector mechanisms'and gears for controlling the operation of the number bearing members.

It is the primary object of the present invention to simplify this structure by dispensing with a number of the parts and at the same time provide a construction where by the operating gears may be arranged compactly in a minimum space, and to this end there is provided a series of gears for each" of the power shafts for imparting a variable movement to the respective operating shafts of the number bearing members of the totalizer and a traveling actuating gear on each of the operating shafts, which gear is common to the gears of the series on the respective power shafts.

A further object is to provide improved selector mechanisms for shifting and positioning the traveling gears with relation to the gears on the respective power shafts.

A further object is to provide improved means for locking the actuated key of any one series in its actuated position and the remaining keys of the respective series against operation when one of the series is actuated.

" A further object is to provide improved means for automatically restoring the'aotu- 'ually and simultaneously releasing all of the actuated keys, individual to the ually releasing the and also improved means series of keys for manactuated key of the respective series.

A further object is to provide improved means common to the keys of the respective series for looking or holding the traveling gears in their normal or inactive position and for releasing the gears by the operation of any one key of the respective series of keys to permit the gears to be correspondingly ad uSted to the proper position by the respective selector mechanisms when the latter are actuated by the keys.

A further object is to provide mechanism of this character which will be simple, dura; ble and cheap in construction, compact in arrangement, and effective and efficient in operatlon.

To the attainment of these ends and the accomplishment of other new and useful ob ects as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings constituting an embodiment'of the invention, in which Figure 1 is a longitudinal sectional view of the keyboard and a portion of the machine, constructed in accordance with the principles of this invention. Fig. 2 is a detail perspective view of a portion of the setting mechanism slide bar. Fig. 3 is a sectional view on line 33 of Fig. 4. Fig. 4 is a horizontal sectional view on line 44 of Fig. 1.

Fig. 8-is a sectional view on line 88 of Fig. 1. Fig. 9 is a plan view of a portion of the keyboard.

Referring more particularly to the drawings and in the present exemplification of the invention, the numerals 15 designate suitable supports, which are spaced from each other and mounted upon the base of the machine. Journaled in these supports 15 are a plurality of power shafts 16, preferably nine in number, one for each of the are journaled in suitable supports, preferably th supports 15, and are arranged in a plane above the shafts 16. One of these power and operating shafts 16, 17 is pro- 'vide'd for each of the number bearing members 18 of the totalizers, and the operating.

shafts 17 are-connected to shafts 19, which latter are arranged in the same plane as the respective shafts 17 by\neans of a pawl and ratchet connection 20, 21, so that when the shafts 17 are rotated in a manner to be hereinafter set forth, the respective shafts 19 Willbe rotated to convey motion to the number bearing members 18 of the totalizers 20 through the medium of a train of connecting gears 22.

J ournaled in suitable supports and preferably in the same plane with the power shafts 16 is a running shaft 23 (see Fig. 4), and

'25 another shaft 24 parallel with the shaft 23' is provided. A shaft 25 is arranged-to extend transversely across the ends of the shafts 16 and is journaled in suitable supports such as brackets'26, and a plurality f gears 27 are provided on this shaft 25, and which gears mesh with gears 28 on the respective power shafts 16. The shaft 25 is also provided with a gear 29, which meshes, with a gear 30 on the shaft 24, by

85 means of which the shaft 25 is rotated from the shaft 24. This shaft 24 receives its motion from the running shaft 23 by means of a gear31, which is mounted loosely upon the running shaft 23. A disk or member 32 is also-mounted loosely upon the running shaft 23 and is connected with 'the gear 31.-

A star or tootned member 33 is'seeured fast to the shaft 23. for rotation therewith, and a pawl 34 is pivotally supported by the disk or member 32 which cofiperates with the star or'toothed wheel 33. An elastic membeiwsuch as a spring 35 is provided which tends normally to hold the pawl 34 in engagement with thestar wheel to lock the gear 31 for rotation withthe' shaft 23. A

gear 36 is secured to the shaft 24 for rotation therewith and meshes with the. gear 31. When the gear 31 is locked to the shaft 23 for-rotation therewith, it will'be apparent as that this motion will be imparted to the shaft 24 through the medium of the meshing gears 31, 36, and when the ar 31 is released and unlocked from its shaft 23 the shaft 24 will remain idle. An operating on key having a stem 37 is provided for controlling this connectlon between the shafts 23 and 24, and this stem is connected to an, arm 38, which is adapted to engage a shoulder 39 on the dog 34 to hold as .the latter out of operative position operating shafts 17, and which latter shafts with respect to the star or tooth wheel 33. When the stem 37 is depressed, to release the dog 34, the power shafts 16 will be set in motion and will continue to rotate as long .as the stem 37 is depressed. If the stem 37 should be depressed sufliciently to release the dog 34 and then immediately released, the arm 38 would assume a position so that when the shaft 23 is completing its revolution, the arm would engage the shoulder 39 of the dog and auto- .matically unlock the gear 31. The specific construction and operation of the abovereferred to parts, however, form no part of the present invention, but constitute a portion of the subject-matter of the application above referred to. The present invention is designed to be associated with this mechanism and comprises a. plurality of mutilated gears 40 On each of the power shafts 16. These gears are preferably nine in number-and are secured together in any desired or suitable manner, and are preferably arranged adjacent one end of their respective power shafts 16. The gears are provided respectively with a different number of teeth from 1 to 9, and are arranged so that the number of teeth will progress successively from one end to the other end of the respective series. The gears 40 on adjacent power shafts are arranged in staggered relation with respect to each other, that is, the gears on one shaft are preferably arranged adjacent one end of one shaft, while gears on the next adjacent shaft are arranged on the opposite end of the latter I shaft so that the shafts 16 may be arranged in close proximity to each other without materially increasing the width of the mechanism. The gears of each of the series are secured to their respective shafts and to each other for simultaneous rotation, and

a travelin gear 41 is mounted upon each of the sha s 17. These gears 41 are secured to their respective shafts 17 for rotation 11o therewith and for adjustment longitudinally on the shaft by means of a key and feather connection 42, and the gears 41 are also afrranged in staggered relation with respect to each other so that they will move adjacent their respective gears 40. The gears 41 are adapted to be moved for any desired distance on the shafts 17, so as to position them with respect to the gears 40 to beengaged by the respective gears when the power shafts 16 are rotatedto impart a degree of rotation to the operating shafts 17 corresponding to the number of teeth on the re spective gears 40,with which the traveling operating gear 41 meshes.

Each of the gears 41 is adapted to be positioned and shifted by means of a series of keys 43, nine of which keys are provided in each of said series Selector mechanisms are provided for each of the gears 41 and 30.

extending longitudinally of and for substantially the entire length of the bar. Recesses 46 are provided in the bar, which open through the edges of the slot 45 and have communication with the slot. These recesses,

46 are arranged in staggered relation with respect to each other for a purpose to be hereinafter set forth. The bar is also provided with recesses &7, which also open through the sides of the slot 45 and have communication therewith. These recesses 47 are preferably formed by cutting out a portion of the material of which the bar is formed and depressing the cut-out portion to form depending lips 48, one of which lips is arranged adjacent to and cooperates with each of the recesses d6. The forward end of each of the bars 44 is preferably reduced as at a9, and extends through a suitable guide 50, and the forward extremities of the ends 49 are bent upwardly as at 51 to form a handle 52 at the extremity thereof, and which handles project through slots 53 in the top 54: of the casing for the mechanism. The rear ends of. the bars 44 are supported in any suitable manner, but preferably by means of fastening devices 55, preferably in the form of headed bolts which project through slots 56 formed by the cut-away portions in the edges of adjacent bars.

Each of the keys 43 is provided with a stem 57, and these stems pass through the top 54 of the casing of the machine and also project through the slot 45 in the respective bars 44. Each stem 57 is provided with a laterally projecting pin 58 which extends over the top of the bar and the projections on the stems extend alternately from opposite sides of the stems. A guide 59 may also be provided through which the stems 57 of the keys 43 pass to assist in supporting and guiding the stems, and an elastic member is provided for each of the bars 44. One end of the elastic member is secured as at 61 to the bar and the other extremity is anchored as at 62 to a fixed support, prefer ably the guide 59. The bar i4 is adapted to be reciprocated in a manner to be hereinafter set forth and constitutes the selector mechanism for positioning the gear 41 with relation to the respective gears 40. In order to accomplish this result, the gears 41 are secured by means of yokes 63 to the respective bar 44, so that when the bar is longitudinally moved or adjusted the gears ll will be correspondingly adjusted and the degree of adjustment of the bar 44 will be controlled by the respective keys 43 of the respective series. The bar 44 is adapted to be held in such a position with respect to the stems 57 of the keys that the recesses 46, when the keys are in an inactive or normal position, will stand below the pins or projections 58 on the respective stems 57, so that when a key is depressed the pins or projections thereon will pass through the respective recesses 4.6 until the pin stands below the bar. When the pin has assumed this position, the elastic member will operate to move the bar 44 longitudinally and in such a direction that the respective depending lip or projection 48 will engage the pin or projection and arrest the movement of the bar. 1V hen the bar is thus shifted, the gear 41 will be shifted and by the time the depending lip or projection -18 engages the pin 58 of an actuated key the gear 41 will have been correspondingly adjusted so that it will be in a position to mesh with the gear of the series l0 which corresponds with the number of the key actuated.

In order to properly position or hold the bar 44 so that the recesses 46 will stand below the pins or projections 58 to receive the latter. a locking member 6% is provided for each series of keys. This locking member may be of any desired or suitable construction, but preferably comprises a bar or member as shown, the extremities 65 of which are bent at an angle to the body portion of the bar, and preferably inclined to one side thereof to form yokes which are pivotally supported upon the respective operating shafts 17 by means of the shafts passing through suitable apertures (36 in the bent extremities 65. Collars (37 may be provided on the shafts 17 and on each side of one of the ends 65 of the yoke for preventing the locking bar from moving longitudinally on the shaft.

Suitable elastic members (38, such .as springs or the like, may be provided for normally holding the locking bars or members M into the path of movement of the ends of the stems-57 of the respective series of keys 43. These elastic .members are secured by one extremity in any suitable manner to the bar 64, and the other extremities thereof are anchored to suitable fixed supports, preferably the guide 59. An elastic member 69 may be provided for each of the keys, and these members surround the stems with one extremity resting upon the guides 59 and the other extremities engaging a pin or shoulder 70 on the stem. The normal tendency of these elastic members (it) is to elevate the keys 43 and to hold them in their normal or inactive positions with the pins or projections 58 on the stems elevated above the bars H. 'hen the keys l3 are in an inactive or normal position, the bars H- are in the positions shown in Figs. 1 and 4 of the drawings, that is to say, in their extreme forward positions, with the elastic members 60 under tension. Any suitable means may be provided for holding the bars in this position. and a suitable and efficient means for accomplishing this result comprises a pro- &

jection 71 on each of the bars or members 64. These projections 71 may be formed in any desired manner, preferably by cutting out a portion of the material of which the bar is formed and bending the cut-out portion at an angle to the body portion of the bar. The bar or member 44 is provided with a depending lip" or projection 72, and the projection 71 is so arranged as to stand within the path of movement of the projection 72 onthe bar or member 44 when the latter is moved by the tension of the elastic member 60 and the locking bar 64 is in its normal position and resting against the ends of all of the stems 57 of the respective series of keys. 43.

It is thought that the operation of this portion of the mechanism will be clearly understood, but briefly stated itis as follows: When the parts arein their no mal or inactive positions, as shown in Figs. 1 and 4 of the drawings, the setting mechanism slidebars 44 ofthe selector mechanisms will be normally held in their extreme forward poitions and the locking bars or members 64 will be elevated by the elastic members 66. so that the end of the stems 57 of all of the keys 43 will rest thereon and the bars 44 will beheld in their extreme forward positions by means of the projections 7 2 thereon engaging the projections 71 on the respective bars or members 64. At the same timethe operating gears 41 of theoperatin'gshafts 17 will be held in their extreme positions and adjacent the mutilated gear having the lowest number of teeth or the gear having one tooth, but out of mesh therewith. Whenever one of the keys of any series is. de-

pressed, the first operation will be to rock the locking bar or member 44 about the shaft 17 so as to move the projections 71 out of the path of movement of the projections 72, after which the elastic member will exert its tension upon the bar 44 to shift the latter longitudinally. Before the elastic member 60 acts andjust before the projec- 'tion 71 passes out of engagement with the projection 72, the pin 58 on the stem 57 on the actuated key will pass through the recess 46 to the under side of the bar 44. The elastic member 60 will then exert its tension on the bar 44 to shift the same longitudinally and the bar will continue to move until the pin or projection 58 is engaged by one of the dependinglips or projections 48 on the bar. This will arrest the movement of the bar under the tension of the elastic member 60. During the movement of the bar 44 under the tension of the elastic member, the gear 41 will be correspondingly shifted until it assumes a position adjacent the gear of the member 40 corresponding to the key which has been actuated, and when the movement of the bar 44 is arrested by the lip or projection 48 engaging the pin 58 the gear 41 will be held in proper position. After the gear 41 has been,thus set, the operator may then actuate the key controlling the stem 37 for locking the gear 31 to the shaft 23 to impart motion from the shaft 23 to shaft 24, and which motion will in turn be imparted to the shaft 25, and from the shaft 25 to the shafts 16. When these power shafts 16 are rotated,

' the respective series of gears 40 will be rotated and the gear 41 will be rotated a number of steps to correspondingly rotate the shafts 17 and ultimately the number bearing 18 of the totalizer, a number of steps equal to the number of teeth on the mutilated gear of the series 40, with which the gear 41 meshes. Just at the completion of one complete revolution of the shafts 16 the arm 38 will trip the dog 34 to unlock the gear 31 from the shaft 23. This operation may be repeated as often as desired. When the selector mechanism or slide-bar 44 has been longitudinally adjusted after one of the keys has been actuated, the recesses 46 on all of the other keys will be moved away from the respective pins 58, and when thus adjusted the actuated key will be locked in its actuated position and all of the remaining keys and efiicient means for accomplishing this pjirpose will now be described.

v In order, to automatically return all of the keys which have been actuated, there is provided a bar or rod 71*, which issupported for pivotal movement by means of arms 7 2 and these arms are pivotally supported preferably upon the shaft 25. These arms 72 are provided with a projection 73, which extends belowthe shaft 25 and is adapted to be engaged by a cam 74, which latter is rotatably mounted upon a shaft 75 (see Fig. 1), and a gear 76 is provided for rotating the cam 74, which gear meshes with a gear 77 on the shaft 25. The gear 77 is mounted loosely upon the shaft 25 and isprovided with a clutch face 78 with which a clutch member 79 coeperates, and this clutch member 79 is keyed to the shaft 25 for rotation therewith.- A lever 80, which extends through the top 54 ofthe casing of the machine, is provided for shifting the clutch member 79. When the clutch member 79 is in engagement with the clutch face 78 of the gear 77 the latter will be locked to the shaft 25, and when so locked will impart ro tation' to the ear 76. As this gear 76 ro tates the cam 4 will rotate and engage the projection 73 'on the'arm 72 to rock the bar 71 to move the latter into engagement with a lip or projection 81 which depends from the forward end 49 of the bars 44. As the bar 71 is rocked, all of the bars 44 will be drawn forwardly so as to create a tension on the elastic member 60. A continued rotation of the cam 74: will permit the bar 71 to be returned to its normal position by means of' an elastic member or spring 72". As the bars 44 are drawn forwardly, the elastic members 68 will return the locking bars 64 to their normal positions so that the projections 71 thereon will be in position to be engaged by the projections 72 on the bars 44.

It will be apparent that the keys in any one series may be released without releasing the remaining actuated keys 'of the other series by simply sliding the bars 4:4 forwardly by grasping the handle 52 of the respective bars, and this may be accomplished without shifting the clutches 79. Suitable mechanisms may also he provided for manually releasing all of the keys which have been actuated, and such mechanism may comprise a bar or plate 82, which is provided with elongated slots 83, through which slots suitable fastening devices 8i pass. This bar or member 82 is preferably supported from the top 54 of the casing, and is provided with a handle 85 which operates in a slot 86 in the top of the casing and extends above the casing. Elastic members 87 are provided for normally holding this bar or member 82 in a retracted position. In operation when any of the keys have been actuated, the handle 52 of the respective bars 44 will assume a position in close proximity to the bar or member 82, and all that is necessary in order to manually and simultaneously release all of the actuated keys, is to grasp the handle 85 and draw the bar or member 82 forwardly against the tension of the elastic members 87, and this will simultaneously adjust the members 44.
